Disk Usage Reports is a free and open source PHP application for displaying and checking website disk usage.
Managing your disk usage can be hard, especially when you’re hosting someone else’s files. The more complex things get, the more insecure they become. Reports are completely static, so there is no chance of server-side vulnerabilities.
The application can collect the data with 3 different methods:
and presents it inside a good-looking, slick interface where you can browse the folders with a tree menu and sort them by name, size or file count.
It can also show the 100 largest files which is great for easily locating the items causing the high disk usage.
The data is stored as JSON (all folders have their own JSON files) and reports are generated on the client-side (which makes the app pretty secure).
